Description

Technical Field

[0001] The utility model relates to the technical field of disinfection equipment, in particular to a disinfection device for plant tissue culture tools. Background Art

[0002] Microbial contamination is a common problem in plant tissue culture. In plant tissue culture, culture medium, inoculation tools, clean benches, inoculation rooms and other working environments need to be disinfected. The disinfection of tools used in tissue culture materials such as stem segment cutting and inoculation is a very important step. Cutting tissue culture materials requires the use of surgical scissors, tweezers, scalpels and other tools. The tools are usually placed on the tool rack on the clean bench. Each time a material is cut or inoculated, the tool needs to be disinfected before cutting or inoculating the next material. Whether the tool disinfection is thorough is related to the occurrence of material contamination. If the tool is not thoroughly disinfected and carries bacteria, once the tissue culture material is contaminated, the cultured seedlings will grow poorly and fail to cultivate, causing great economic losses to factory breeding.

[0003] In the prior art, plant tissue culture tools such as surgical scissors, tweezers, and scalpels are placed on a tool rack on a clean bench in an inoculation room, and an open glass bottle and an alcohol lamp containing 95% alcohol are prepared next to the tool rack. During disinfection, the alcohol lamp is first lit, and the tools are soaked in the 95% alcohol in the open glass bottle, and then the tools are repeatedly burned and disinfected on the flame of the alcohol lamp using the flammability of alcohol. Although disinfection in this way has a disinfection effect, 95% alcohol is a flammable and explosive product. If it is improperly operated during use, it will be dangerous. After the tools are burned and disinfected, the tools are too hot to easily damage the incision of the tissue culture material, so that the tissue culture material cannot develop normally or burns to death. Sometimes the residual alcohol after soaking will flow back to the handheld knife handle along the wall of the surgical scissors and the wall of the tweezers, scalding the hand.

[0004] In order to overcome the shortcomings caused by alcohol lamp disinfection, a kind of infrared inoculation loop sterilizer (model HY-800D) has also been developed in the prior art, which is mainly composed of a support, a heating cover and an infrared heating tube in the heating cover, and the heating cover is installed on the support. When it is in use, the switch is first turned on, and then the heating tube starts to heat up to the expected temperature, and then the staff holds the articles that need to be sterilized, so that the parts that need to be sterilized on the articles are located inside the heating cover, and the radiation generated by the infrared heating tube heats the articles, and then the parts that need to be sterilized on the articles are sterilized by high temperature. However, it is necessary to hold it in the heating process, which will undoubtedly increase the labor burden of the staff.

[0005] In addition, the tools after disinfection need to be placed on the tool rack. The existing tool rack is a bottom plate with two tripods connected at both ends. There is a movable saw blade between the tops of the two tripods for placing tools. However, when the tools are frequently disinfected, the tool rack is prone to shaking during the process of taking and putting tools, and its length is limited. When there are many tools, they are placed too densely. When taking and putting tools, they will collide with the tools next to them, causing the tools next to them to fall from the side of the tool rack. This is also easy to be contaminated with bacteria and other microorganisms, causing contamination when cutting or inoculating materials.

[0006] Therefore, there is an urgent need in the art for a novel sterilizing device for plant tissue culture tools to solve the above problems. Utility Model Content
